EDWIN REYNOLDS, OF MILVAUKEE, VISCONSIN.

STEAM-BOILER.

SPECIFICATION forming part of Letters Patent No. 394,211, dated December 11, 1888.

Application filed August 2, 1888. Serial No. 281,752- (No model.)

To all whom it may concern.-

Be it known that I, EDWIN REYNOLDS, of Milwaukee, in the county of Milwaukee and State of \Visconsin, have invented certain new and useful Imprbvemei'its in SteanrBoilers, of which the following is a specification.

My invention relates to that class of boilers known as tire-tube, and it consists in a novel arrangement of the tubes or flues and in the hand-holes or openin affording access to the same, all as hereinafter fully set forth and claimed.

In the drawings, Figure 1 is a Vertical central sectional View of my improved boiler, and Fig.2 a horizontal sectional View on the line A indicates the shell of the boiler, 13 the head, and C the crown-sheet, all of which will be made of steel.

D indicates the shell of the tire-box, which is separated from the shell of the boiler, so as to form a water-space, E, as shown in Fig. 1, the lower end of the water-space bein closed by a metallic rin F F indicate the tubcsin the present instance one hundred and twenty-tom in number-which are secured at opposite ends to the head I) and crmvmsheet but instead of arranging these tubes or flu es in parallel lines, as has been customary, they are arranged in lines radial to a man-hole or openii'ig, G, in the shell of the boiler about on line with the crown-sheet, as shown in 1. Similar but smaller holes or openings, G, are made in the shell of the boiler on the rear side, as shown .in both figures, these openings permitting the scraper to pass through the boiler from side to side and thereby remove from the upper face of the crown-sheet sediment and dirt scraped from the exterior of the t1 ues.

The openings G will of course be provided with suitable caps or covers, II, which may be of any suitable construction.

The arrangement of the fines in lines radial to the man-hole G enables all parts of the tube-sheet and all of the tub es to be examined and cleaned by removing the man-hole cover.

The sediment and dirt which fall into the bottom of the water-space E may be removed through a blow-off pipe, I, (shown in dotted lines in Fig. 1 and in full lines in Fig. 2,) and to further insure the proper cleaning out of this space the shell of the boiler is provided with six (more or less) hand-holes, J, provided with suitable covers, K.

No claim is made herein to the feed-water purifier, as that will form the subject-matter of a separate application in accordance with an official requirement to that eitect.

Having thus described my invention, what I claim is- 1. In a tubular boiler, the combination, with a shell and a man-hole or opening therein, of a series of dues or tubes arranged in lines radial to the man-hole.

2. In a tubular boiler, the combination, with a shell and a man-hole or opening therein, of a series of fines or tubes arranged in lines radial to the man-hole and one or more openings in the shell opposite the man-hole.

In a tubular boiler, the combination, with a shell and the crown-sheet and cap, of a manhole or opening in the shell about 011 line with the crown-sheet, and a series of fines secured at their ends to the crown-sheet and cap and arranged in lines radial to the man-hole, all substantially as shown.

4,. In combination with the shell A, cap B, and crown-sheet G, a man-hole, G, in the shell about on line with crown-sheet C, flues F, arranged in lines radial to the man-hole or opening, and openings G in the shell opposite to the man-hole, all substantially as shown.

In witness whereof I hereunto set my hand in the presence of two witnesses.

EDWIN REYNOLDS.
